仅显示一次列值

Question

假设我有下表.如何根据列仅显示"金额"一次ID？

   ID     Amount 
    1      10.00  
    1      10.00  
    1      10.00  
    2      10.00
    2      10.00
    2      10.00

鉴于ff示例,预期输出应如下所示:

   ID     Amount 
    1      10.00  
    1      0.00  
    1      0.00  
    2      10.00
    2      0.00
    2      0.00

我试过用ROW_NUMBER但不够,给我这个结果.

   ID     Amount 
    1      10.00  
    1      0.00  
    1      0.00  
    2      0.00
    2      0.00
    2      0.00

编辑:这是我到目前为止尝试的:

SELECT ID
       ,CASE WHEN ROW_NUMBER() OVER(PARTITION BY Amount ORDER BY ID) = 1  
            THEN Amount
            ELSE 0.00
        END [AMOUNT]
FROM TABLE

只需更改您的分区即可使用ID:

SELECT ID
       ,CASE WHEN ROW_NUMBER() OVER(PARTITION BY ID ORDER BY ID) = 1  
            THEN Amount
            ELSE 0.00
        END [AMOUNT]
FROM TABLE
Order by ID, Amount Desc
